As I mentioned in a previous message, I have an HP 3816A GPS timing
receiver. I was interested in seeing if I could find a way to convert
the 19.6608 outputs into being extra 10 MHz outputs.

Well I hacked mine and made a mod that seems to work for me. I'm not
sure if this will work for others, as I found some factory installed
rework wires right in the area where I made the changes. If someone
wants to attempt what I did and doesn't find the same factory jumpers,
it might require more snooping like I did.

Anyway, if anyone wants to look at what I did and some notes on what I
learned about the main board, here is a link to a write-up I did...
